Study of Difluprednate Ophthalmic Emulsion in the Treatment of Severe Uveitis

A Phase 3 interventional study of Difluprednate Ophthalmic Emulsion in Uveitis and Panuveitis, sponsored by Sirion Therapeutics, Inc.. Completed. Open to participants aged 12 Years and older. Per ClinicalTrials.gov, last updated 2006-12-04.

Primary conditionPanuveitisRegistry: UveitisReclassifiedWhy we changed it
Registry
Uveitis — the first condition term the registry derived for this study.
ClinicalTrials.gg
Panuveitis
Why
  1. The study's listed conditions name Panuveitis, a narrower term within Uveitis.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

The purpose of this phase 3 open-labeled study is to determine if difluprednate ophthalmic emulsion is effective in the treatment of severe uveitis.

Read the detailed description

The objective of this phase 3 study is to assess the efficacy and safety of 0.05% difluprednate ophthalmic emulsion in patients with severe endogenous anterior uveitis with an open-labeled, no-controlled and no-randomized design.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Patients with a diagnosis of endogenous anterior uveitis or panuveitis
  • Patients with ≥ 50 anterior chamber cells as observed by slit lamp microscopy (criterion for evaluation of signs 4)
  • Patients requiring more frequent instillation of 0.1% betamethasone sodium phosphate ophthalmic solution than the regular frequency specified in its dosage and administration (3 - 4 times/day)
  • Patients aged ≥ 12 years (on the day of obtaining ) who were able to actuate symptoms
  • Patients giving written informed consent prior to initiation of the study

Exclusion criteria

Exclusion Criteria:

  • Patients who did not meet all of the above inclusion criteria
  • Patients initiating treatment with systemic administration of any , non-steroidal anti-inflammatory drug, antiphlogistic enzyme or drug within 2 weeks before instillation of the drug
  • Patients receiving topical injection of any corticosteroid in eyes before instillation of the investigational product(solution formulation: within 1 week before instillation of the investigational product, depot formulation: within 2 weeks before instillation of the investigational product)
  • Patients receiving instillation of any corticosteroid, non-steroidal anti-inflammatory ophthalmic solution or antiphologistic enzyme within 12 hours before instillation of the investigational drug
  • Patients with glaucoma or ocular hypertension
  • Patients with corneal erosion or corneal ulcer
  • Patients with any viral, bacterial or fungal keratoconjunctival disease or suspected with eye infection
  • Patients with allergy to similar drugs of difluprednate
  • Patients requiring use of contact lens during the study period
  • Women who were or might be pregnant, or lactating women
  • Patients participating in another clinical study within 3 months before initiation of the present study
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What researchers measure

Primary outcomes

  1. The anterior chamber cell score was compared between baseline and Day 14.

Secondary outcomes

  1. The anterior chamber cell score was compared between baseline and Days 3 and 7.

  2. The total symptom score (sum of eye pain, photophobia, blurred

  3. vision, foreign body sensation and lacrimation scores) and total

  4. sign score (sum of anterior chamber cell, anterior chamber flare,

  5. ciliary hyperemia, keratic precipitate and synechia of iris and

  6. posterior scores) were compared between baseline and Days 3, 7

  7. and 14.
